Not really comparable since the RG doesnt have a baseball field to water... but the toilet idea is a good one. Rose Garden has GOLD LEED Certification... first major sports facility to do so. Boo ya! http://www.nba.com/blazers/news/leed_certification.html
Yeah, I know the RG is awesome for that stuff, but there's no reason we can't keep getting better. I didn't consider the part about watering the field; good call!
